Note that this is not cross-compilation, and indeed, if you’re on
x86_64, you don’t need to cross-compile since you can natively run i686
code.
I think you can do something like:
(define gcc/i686
(package
(inherit gcc)
(arguments `(#:system "i686-linux"
,@(package-arguments gcc)))))
and that should give you the i686-linux GCC package, regardless of what
platform you’re on (use with care!).
Is it what you tried?
Thanks,
Ludo’.
